Show Your Fangs. The E2D Defender® Ultra is a superlative everyday-carry tactical light. Machined from aerospace aluminum, every Defender body incorporates a crenellated Strike Bezel® and scalloped tailcap that turn these robust illumination tools into formidable weapons, just the thing for when a thorny situation can’t be solved by photons alone. Its intense 1,000-lumen beam delivers a crucial tactical advantage by providing blinding white light to disrupt an attacker's night-adapted vision. Focused through our TIR lens, it provides a far-reaching beam for positive threat identification plus plenty of spill light to help you maintain situational awareness. The Defender is engineered to take a beating—or even give one if it's necessary to save your life.FEATURES: Virtually indestructible LED is regulated to maximize output and runtime Choose between 1,000 lumens of intense high output or 5 lumens of low output for map reading and other tasks TIR lens produces a tight beam with significant reach and enough surround light for peripheral vision Mil-Spec Hard Anodized for durability and corrosion resistance Crenellated Strike Bezel® and scalloped tailcap provide enhanced self-defense capabilities Includes high-energy 123A batteries with 10-year shelf life Dual function stainless steel clip for bezel-up or bezel-down pocket storage SPECIFICATIONS: Key attributes High output: 1,000 lumens High runtime: 2.75 hours Peak beam intensity: 10,600 candela Batteries: Two 123A (incl.)
